Stennis conducts launch acoustics testing. Operators at the E-3 Test Stand at NASA's John C. Stennis Space Center conducting acoustics testing in 2010. The tests are designed to gather critical information for future space launches. Stennis operators investigated lift-off acoustics that can damage space vehicle components by testing the benefits of injecting water onto the upper surface of the launch pad to suppress sound. The Stennis tests provided critical data to determine what can be gained from this approach. Credit: NASA #NASA NASAStennis #technologytuesday #Stennis #rocketscience
